The Electorate of Württemberg was a short-lived state of the Holy Roman Empire on the right bank of the Rhine. In 1803, the Imperial diet raised the Duchy of Württemberg to an Electorate, the highest form of a princedom in the Holy Roman Empire. However, soon afterward, on 1 January 1806, the last Elector assumed the title of King of Württemberg. Later, the last Emperor, Francis II, abolished de facto the empire on 6 August 1806.
